Hi all! I'm new on this forum, so i beg your pardon if i'm doing something against its rules!
Anyway, I have this problem: I'm using the XMC4800 relax kit to implement an EtherCAT slave (using the code of the example i've found at this page: https://www.infineon.com/cms/en/product/promopages/aim-mc/dave_downloads.html) and I want my slave to send a master the result of the QSPI test (the one i've downloaded from the page i've previously linked).
I notice that, if i don't insert that test into an EtherCAT system it works fine, but when i try to insert it into the main of the EtherCAT code, it always fail. I've checked the Chip Select pin of the flash memory: with the EtherCAT, the memory seems to be selected for fewer time (i.e. the time during which the chip select is driven low is almost the half of the case without the EtherCAT).

Which could be the problem and how could I solve it?
Thanks in advance!
